Engineered for seamless compatibility across Olympus®, Fujifilm®, Pentax®, and standard therapeutic flexible endoscopes and ureteroscopes.
A technical assessment of why tier-one hospital procurement networks and medical distributors are shifting from legacy reusable tooling to micron-tolerance sterile single-use devices.
Micro-lumen reprocessing failure remains one of the primary vectors of carbapenem-resistant Enterobacteriaceae (CRE) transmission. Precision single-use EDS instruments eliminate sterilization cross-contamination risks entirely.
The total cost of ownership (TCO) for reusable endoscopy instruments—factoring autoclaving, specialized labor, enzymatic detergents, channel wear, and repair—frequently exceeds the per-case cost of dedicated single-use devices.
Modern EDS procedures (EMR, ESD, ERCP, and complex RIRS lithotripsy) require micro-actuation mechanics capable of 1:1 tactile torque transmission through highly tortuous anatomical pathways.
Inside Jiangxi ZhuoRuiHua Medical Instrument Co., Ltd. (ZHR Med) – high-throughput automated manufacturing, rigorous ISO 13485 cleanrooms, and vertical integration from raw alloy to sterile blister pouch.
All EDS instrument assembly, catheter tipping, handle joint swaging, and primary sealing take place within certified Class 100,000 (ISO Class 8) cleanroom environments with continuous airborne particulate monitoring.
Multi-axis Swiss precision turning machines sculpt biopsy jaws, fenestrated graspers, and rotatable hemoclip housings directly from surgical-grade medical stainless steel bars with micron-level concentricity.
Pulsed fiber laser micro-welding ensures structural cohesion between driving cables and mechanical linkages, providing ultra-high tensile safety factors that prevent mechanical dissociation inside patient anatomy.
Every single snare wire loop, biopsy forceps linkage, and hemoclip trigger cable undergoes automated tensile testing, rotation smoothness profiling, and release force validation before entering the packaging cell.

Our factory manufactures 19 core device categories organized under six primary clinical pathways: 1. Tissue Sampling: Single-use biopsy forceps (oval, alligator, with/without needle), hot biopsy forceps, cytology brushes. 2. Hemostasis: Repositionable 360-degree rotatable hemoclips and endoscopic ligation devices. 3. EMR/ESD: Single-use cold/hot polypectomy snares (crescent, oval, hexagonal), endoscopic injection needles, sclerotherapy catheters. 4. ERCP: Disposable sphincterotomes (double/triple lumen), nitinol-core hydrophilic guidewires, naso-biliary drainage catheters. 5. Endourology: Sterile negative-pressure suction ureteral access sheaths, tipless nitinol stone extraction baskets. 6. Reprocessing & Accessories: Bite blocks, channel cleaning brushes, valve covers. All categories are available for OEM, ODM, and ZhuoRuiHua branding.
Every single model number has defined outer diameter (OD) and working length (WL) tolerances designed strictly against standard working channel diameters (e.g., 2.0mm, 2.8mm, 3.2mm, and 3.7mm). For instance, our biopsy forceps designated for 2.8mm channels have an outer sheath diameter strictly held within 2.30mm ± 0.05mm, coated with low-friction fluoropolymers to prevent internal channel scratching even through severe 210-degree scope retroflexion.
We provide comprehensive technical dossier support tailored to national authorities, including ISO 13485:2016 certificates, CE Certificates of Conformity under MDR, Declarations of Conformity (DoC), ISO 11135 ethylene oxide sterilization validation reports, ISO 10993 biocompatibility testing suites, accelerated 5-year packaging aging test data (ASTM F1980), transit simulation reports (ISTA 2A), and factory Certificate of Analysis (CoA) per lot shipment.
We operate in-house tooling, CNC precision turning, plastic injection molding, and catheter extrusion. For custom sheath lengths, snare loop geometry adjustments, or specific handle ergonomics, rapid 3D prototyping is delivered within 7 business days, with pilot injection mold tooling completed in 25–35 days. Standard private-label packaging MOQs generally start at 500–1,000 units per SKU, while high-volume bulk supply contracts benefit from tiered factory-direct pricing.
